DiskStation DS1515+

Quad-core CPU for blazing-fast performance

DS1515+ is powered by a quad-core CPU running at 2.4 GHz. Combined with 2GB of DDR3 RAM (expandable to 6GB), it delivers blazing-fast performance over 450.77 MB/s reading and 396.5 MB/s writing.1 That much power makes it easy for DS1515+ to multitask and provide consistently high throughput to all connected clients.

Fast encrypted data transmission with AES-NI

Encrypting data is essential to a healthy security policy. Equipped with a dedicated hardware encryption engine, DS1515+ is the ideal digital locker for sensitive data; files and folders are encrypted on the fly without any perceived performance loss. DS1515+ delivers encrypted data transmission speeds over 448.71 MB/s reading and 191.12 MB/s writing.

Quad LAN ports for failover and Link Aggregation support

Equipped with four Ethernet ports featuring failover and Link Aggregation support, DS1515+ ensures continual network uptime even if LAN connection malfunction occurs on one port, reducing the chance of service disruption and costly downtime. Link Aggregation improves connection speeds beyond the limits of a single network cable or port.

Robust scalability up to 90TB

As your data storage needs grow, DS1515+ can be connected to dedicated DX513 expansion units2 for additional storage on the fly, growing capacity with minimal effort. With two DX513 expansion units connected through specially designed eSATA connectors, raw capacity can be as high as 90TB3.

Easy installation, hassle-free maintenance

Easy installation and hot-swappable hard drive support ensures easy maintenance and continuous service uptime should a hard drive need replacement. In addition, DS1515+ incorporates a passive cooling design to reduce dependency on the dedicated processor cooling fan, thus mitigating any critical point of failure. When the system detects a fan failure, the built-in redundancy mechanism ensures continuous operation until the replacement fan arrives.

USB 3.0 and eSATA ensure speedy transfers to external storage

DS1515+ boasts USB 3.0 and eSATA ports to connect to various kinds of external storage devices, while ensuring fast and efficient file transfer speeds. Support for USB 3.0 offers transfer speeds of up to 5 Gbps (about 10 times faster than USB 2.0), meaning it takes less time to transfer data to external hard drives, while also consuming less power.

Ensuring business continuity

Uninterrupted availability is a critical goal for all businesses. DS1515+ supports Synology High Availability (SHA) technology which combines an active and passive server into one cluster, the former always mirrored to the latter. The Heartbeat mechanism detects regular "heartbeats" between the two servers. If the main server encounters unexpected downtime, the passive server immediately takes over. With multiple LAN ports, DS1515+ also ensures redundancy in the event of unexpected network failure. Learn more

Effective backup solution

Synology DS1515+ can serve as a centralized backup target. Whether you are a Windows or Mac user, you can back up everything on your computer directly to Synology NAS using Cloud Station. Whenever you modify a file, the changes are backed up to DS1515+ automatically. Mac users also enjoy native Apple® Time Machine support. You can also back up data from your DS1515+ to another DiskStation, rsync servers, external drives, or even Amazon® S3, Glacier cloud service, Microsoft Azure, SFR, and hicloud. "Backup & Replication" allows you to schedule backup tasks and restore the server to any particular point in time, while minimizing storage consumption and processing time by saving only the specific data block that has been changed between versions.

Increase business productivity with cloud solutions

With comprehensive cloud solutions, DS1515+ lets you create your own private cloud easily. Cloud Station is the perfect package to sync files across multiple devices. Files can be edited in offline mode and later synced to Cloud Station, which keeps up to 32 historical versions, allowing you to restore a file back to previous version or recover deleted files. With the mobile app DS cloud, any change made to a file is automatically synced to your smartphones and tablets. For distributed enterprises, Synology's 2-way sync between different DiskStations ensures employees at different locations share the same information in real-time. IT administrators can handpick individual folders that they want to sync to different devices, manually or automatically based on file format and size. Folders synced by Cloud Station can be encrypted on DSM — no one will be able to access its content without your private key. Learn more
